	1	Piezoelectric and ferroelectric properties of Na_(0.5)Bi_(4.5)Ti_(4)O_(15)-BaTiO_(3) composite ceramics with Mg doping显示文摘As one of the representatives of lead-free NBT ceramics,Na_(0.5)Bi_(4.5)Ti_(4)O_(15) has still attracted much attention due to its excellent dielectric properties and has become the focus of research.However,its piezoelectric properties are far from satisfactory.In order to improve the piezoelectric properties of Na_(0.5)Bi_(4.5)Ti_(4)O_(15),Na_(0.5)Bi_(4.5)Ti_(4-x)Mg_(x)O_(y)–BaTiO_(3)(NBTM–BT)composite ceramics were synthesized by a conventional mixed oxide route and sintered at 1040℃ through two-step method.We optimized the electrical properties of NBTM–BT by changing the stoichiometric ratio of Mg content and studied its microscopic mechanism.The piezoelectric coefficient(d33)is stable at about 20 pC/N.Moreover,the maximum remanent polarization(2Pr)of the ceramic is 3.08C/cm^(2) with the coercive field of 18.01 kV/cm.The dielectric constant and dielectric loss for Na_(0.5)Bi_(4.5)Ti_(3.96)Mg_(0.04)–BT composite ceramic were found to be 486 and 0.17 at 10 kHz,respectively.The characteristic peaks of BT and Na_(0.5)Bi_(4.5)Ti_(4)O_(15) can be observed clearly from the X-ray diffraction analysis.SEM analysis showed that all samples were well crystallized.Consequently,the piezoelectric and ferroelectric properties of Na_(0.5)Bi_(4.5)Ti_(4)O_(15)–BT composite ceramic will be enhanced much by Mg doping,which means it has a wider range of applications in electronic devices such as piezoelectric devices.
